This HP Z8 G4 is a tower workstation built around two 16-core Intel Xeon Gold 6242 CPUs at 2.80GHz and 128GB of DDR4. Storage is a 2TB 7.2K SATA hard drive and a 512GB NVMe SSD, 2.51TB in total in one bay of the 4-bay 3.5-inch chassis, so three remain open for expansion.
Around that sit integrated SATA RAID, 1GbE networking (Intel I219LM) and a 1125W power supply. The configuration also lists Windows 11 Pro as the listed operating system.
Professional graphics (NVIDIA RTX 4000 Ampere) and 128GB make this a practical seat for engineering design, product visualisation and video work.
Memory here is twice that of a lighter Z8 G4 configuration, leaving more headroom for memory-bound work. The Gold processors are a tier up from the entry Z8 G4 builds.
Sold as certified refurbished, the workstation passes inspection and a bench test, and has its storage wiped, in Johannesburg before release.
